Factors affecting loggerhead shrike mortality in Virginia
I studied loggerhead shrikes (Lanius ludovicianus) in the Shenandoah Valley in Virginia from April 1987 to April 1988; factors affecting mortality rates wring the breeding season, fall dispersal, and winter were investigated., The high reproductive,success in this study was similar to that reported …

Status and breeding ecology of the loggerhead shrike in Virginia
Although loggerhead shrikes (<i>Lanius ludovicianus</i>) are still relatively widespread, Breeding Bird Survey results indicate that breeding population have declined substantially in Virginia and other parts of the species' range. Loggerhead shrikes should be considered for federal threatened …

Loggerhead shrike (<i>lanius ludovicianus L</i>) foraging patch and perch selection
<p>Loggerhead shrikes have disappeared across much of their former range, most likely due to habitat loss. I studied the habitat shrikes prefer for foraging. Shrikes forage from a perch on prey that they see in the surrounding vegetation. When I mowed the vegetation on one side of selected perches, …

Historical Responses Of Marine Turtles To Global Climate Change And Juvenile Loggerhead Recruitment In Florida
… II, I reveal a life history characteristic of loggerhead turtles previously undocumented. I identify a pattern of juvenile recruitment to foraging grounds proximal to their natal nesting beach. This pattern results in a predictable recruitment pattern from juvenile foraging ground aggregations …

Development and application of a multistate model to the northern subpopulation of loggerhead sea turtles
Loggerhead sea turtles (Caretta caretta) are listed as threatened under the Endangered Species Act and are protected both on nesting beaches and in United States waters. Loggerhead sea turtles are long-lived species and are most easily studied on the beaches during the nesting season. Bald Head …

Loggerhead (Caretta caretta) and Leatherback (Dermochelys coriacea) nesting activity along the Maputaland coast (South Africa) : 1965 - 2002
From 1963 until the present, loggerhead (Caretta caretta) and leatherback (Dermochelys coriacea) female turtles nesting on a 56-km stretch of beach in Maputaland, on the northeast coast of KwaZulu-Natal, South Africa have been tagged and monitored. In this study, population trends, size, preference …

Reproductive success of sea turtles nesting on Wabasso Beach, East-Central Florida
During the summers of 1988 and 1989, nests of 528 loggerhead sea turtles (Caretta caretta), 27 green sea turtles (Chelonia mydas), and 1 leatherback sea turtle (Dermochelys coriacea) were monitored on Wabasso Beach in Indian River County, Florida. Two hundred and forty four of the loggerhead and 2 …

Effects Of A Shore Protection Project On Loggerhead And Green Turtle Nesting Activity And Reproduction In Brevard County, Florida
… species. The impacts of beach restoration on loggerhead turtles (Caretta caretta) and on green turtles (Chelonia mydas) were investigated. Previous studies concerning beach nourishment projects have focused on loggerhead turtles. I compared data between nourished and non-nourished areas and …

Maternal Plasma and Corresponding Egg Yolk Hormone Variation within a Clutch and Across the Nesting Season of the Loggerhead Sea Turtle (Caretta Caretta)
… of maternally derived egg yolk hormones of the loggerhead sea turtle (Caretta caretta) within a clutch and with increasing nest events across the season. The quantification of the relationship of yolk hormones to maternal circulating plasma hormones also was examined. Estradiol (E2) and …

Nesting Behavior, Growth Rates, and Size Distribution of Loggerhead Sea Turtles (Caretta Caretta) on Blackbeard Island National Wildlife Refuge: An Evaluation of Recruitment In Georgia
An eight year study of loggerhead sea turtles (Caretta caretta) was conducted on Blackbeard Island National Wildlife Refuge (BLB NWR). A 3 month in-water survey also was conducted in 2008 along the coast of Georgia and Northern Florida. The nesting trends on BLB NWR were evaluated to provide …

Variation in Egg Components: A Study of Maternal Investment and Resource Partitioning in the Nesting Loggerhead Sea Turtle; Estimating Genic Variation and Mapping Genetic Lineage of a Rare Captive Helodermatid Population: <em>Heloderma Horridum Charlesbogerti</em>
<p>Loggerhead sea turtles have the highest egg yields of any oviparous non-avian reptiles. Blood urea nitrogen levels increased as the season progressed while total blood albumen and total protein levels decreased. Wet egg mass (H = 1.7719 df = 2 p = 0.0375*) and albumen mass (H = 6.0507 df = 2 p = …
